摘要:In this investigation, the production of bioethanol on the raw sugar beet juice by Saccharomyces cerevisiae was studied. Following cultivation techniques for bioethanol productions were used: batch, fed batch and repeated batch. In batch process substrate conversion coefficient (YP/S) was 0,375 g/g, bioprocess effi eciency (E) 69,70 % and productivity (Pr) 0,53 g/Lh, respectively. During fed batch process bioprocess efficiency parameters have following values: YP/S = 0,502 g/g, E = 93,4 % and Pr = 0,50 g/Lh. Furthermore, in repeated batch process bioprocess efficiency parameters have following values: YP/S = 0,360 g/g, E = 66,91 % and Pr = 0,66 g/Lh. On the basis of previously presented results it is clear that fed batch and repeated batch processes have considerably higher potential for use in the industrial bioethanol production although further optimization of repeated batch cultivation techniques has to be performed.
